There would be no issues if the EU had not gone Crawling to Southern Ireland the country Gearge Osborne bailed our with 9 billion Euros after the crash by the way !
Peter Bone today stated it was only the EU who wanted a hard border - if we leave on WTO rules we can determine a free tarrif in Ireland or if we strike a deal on trade like wise - Peter Bone stated it was basically stirring a storm in a teacup basically the EU spreading manure!!
I apologise in advance again Joe, but that is not true either. The WTO have what's known as 'most favoured nation' rules, which basically mean that unless you have a bona fide trade deal with a nation, you can't offer a preferential deal to one WTO member without having to offer it to everyone.
In other words, we could have a free trade deal with Ireland that has no tariffs, or we could offer all WTO members a no tariff arrangement, but we couldn't under WTO rules offer one to Ireland in isolation.
